The AF 50mm F1.4 FE II lens delivers a 45.7 degrees angle of view on full-frame and 31.1 degrees for APS-C sensors, as well as a bright maximum aperture of F1.4, as preferred by full-frame camera users. Optimum resolution is achieved through the advanced optical design, using 11 lens elements in 8 groups (including 2 ASP, 3 HR, and 1 ED). Combined with Sony's full-frame image sensor, this lens delivers superior sharpness and contrast in all areas of the image.
